我的 iPhone 应用程序可以与连接的计算机通信吗？
最好是通过电缆连接的计算机，但如果有办法通过 WiFi 进行连接，那么这也会很有用。我想知道他们之间是否可以发送消息？
或者，如果我有一个 Mac 应用程序和一个 iPhone 应用程序，我可以通过 wifi 或 USB 连接在它们之间进行通信，而不是使用服务器或其他东西吗？
Preferably, this would be a computer connected via cable, but if there's a way to do it over wifi then this would also be useful. I'm wondering if it's possible to send messages between them?
Or if i had a mac app and an iPhone app, could I communicate between them over wifi or a usb connection, rather than using a server or something?

通过 WiFi 连接是可能的，但电缆连接是不可能的（当然不在记录的 API 中），除非手机已越狱。
对于 wifi，您只需连接到 TCP/IP 主机/套接字。看看 CocoaAsyncSocket。计算机需要托管某种服务器软件。这就是 iTunes Remote 和 AirMouse 的工作原理。
Connecting over WiFi is possible, cable connection however isn't possible (certainly not in the documented API) unless the phone is jailbroken.
For wifi you're just going to connect to a TCP/IP host/socket. Have a look at CocoaAsyncSocket. The computer would need to be hosting some sort of server software. This is how iTunes Remote and AirMouse work.
有一些“允许的”（非破解手机）方法可以将数据从物理插入的设备发送到 iPhone。有多种条形码读取器（例如美国 Apple 商店中使用的 Linēa-pro）以及信用卡磁条读取器（例如，Macally Quikswipe）可以向/从 iPhone 发送有限数量的数据。
如果您的计算机是小型嵌入式设备并且您的数据需求很少，那么这是可能的。
There are some "permitted" (non-cracked phone) ways to send data to the iPhone from a device that's physically plugged in. There are several barcode readers - like the Linēa-pro used in US Apple stores - and magstripe readers for credit cards (e.g., the Macally Quikswipe) that can send limited amounts of data to/from the iPhone.
If your computer is a small embedded device and your data requirements are meager, it may be possible.
